Yes:

edd at max:~$ ldd /usr/lib/R/bin/exec/R  | head -2
        linux-vdso.so.1 =>  (0x00007fffcadd2000)
        libR.so => /usr/lib/libR.so (0x00007fa1e1379000)
edd at max:~$ 

It has been a shared library build since "forever". We used this fact with
other embedding solution (eg rkward, RInside, littler, ...)

You may need to work with the StatET folks.
